Textile Penetrant JFC (Fatty Alcohol Polyoxyethylene Ether)
CAS Number: 34398-01-1
Penetrant JFC is a fatty alcohol polyoxyethylene ether nonionic surfactant providing rapid and uniform wetting of cotton, polyester, and wool textiles before and during dyeing and finishing. It significantly reduces the surface tension of process liquors to ensure complete fiber penetration. Widely used in scouring, bleaching, and dyeing pre-treatment processes across the textile wet processing industry.
